A25T-250-16-1/2 Temperature Swichgage (10703694)

A25T-250-16-1/2: 2-1/2" Temperature Swichgage; polycarbonate case; 130-250 temp; 16 ft lead (10703694)

A25T-250-16-1/2 Temperature Swichgage is a diaphragm-actuated, 2-1/2Ó (64 mm) dial temperature-indicating gage, with a built-in electrical switch for tripping alarms and/or shutdown devices. This rugged, built-to-last instrument is fully sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel, and O-ring seals.

This vapor actuated gage Features a sealed sixteen foot (16Õ) capillary tube, a sensing bulb, and a 130-250¡F (54-121¡C) temperature range.

For series A25T, the gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contact(s) are isolated from ground. They have a self-cleaning motion to enhance electrical continuity. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against the diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading.
